Keeping on the same page when I refresh a grid

So I have a grid with 10 pages. I am on page 5. I refresh the grid because my actions might have caused a number of rows to disappear. When I get the data and rebind, how do I go the the last page I had selected? I want the grid to be on page 5 after the refreshing of the data.

this.WebDataGridView.Behaviors.Paging.PageIndex  

I think this has what I am looking for.

Ah... Not as easy as it first looks. I looked at a couple of other post and can get the current page number. I do it with a hidden control on the client. Now I need to set the page index. I tried on a test button on the form that sets the DataSource and I call DataBind(). I then try to set the pagIndex

.Behaviors.Paging.PageIndex

this nas no effect. Where should I do this?

Hello mland,

you should be able to change page index on a button click. What is your datasource?

Hello mland,

try with this:

    protected void Button1_Click1(object sender, EventArgs e)
    {
        WebHierarchicalDataGrid1.GridView.Behaviors.Paging.PageIndex = 2;
    }

So that works great on a button click. I tried to move it into Page_Load event. I am trying to set the page if it is a postback

if (!IsPostBack)

{

this.RequestGrid.DataBind();

WebHierarchicalDataGrid1.GridView.Behaviors.Paging.PageIndex = 2;

}

On my demo grid this worked great.

On my real grid I got an error, I turned off tracing and it worked. Seems a little odd.

Multiple controls with the same ID 'grdOffRequests:_ctl0:it1_0' were found. Trace requires that controls have unique IDs.
